A CORPORATION CF DELAWARE LOCOOTIVE TENDER CONSTRUCTION Application led Bec-amber 4, 1930, Serial No. 499,894. Renewed March 10, 1932.

Our present invention is directed to impr vements in locomotive tender construction and particularly appertains to locomotive tenders arranged to carry a movably or swivelly mounted Stoker trough. rllhis type of locomotire tender heretofore has embodied a centrally and longitudinally disposed rectangular shaped stoher trough compartment formed by fabricated plates, which compartment in height extended from the top surface of the tender frame to the floor of the fuel section and was of sufficient width to allow for maximum lateral movement of the swinging trough. Such swinging type of trough is usuarly mounted in the compartment to move laterally and vertically about a fulcrum point formed by rollers or equivalent devices. Ordinarily a compartment 35 to 44 wide is sufficient to receive the trough and allow lateral movement such that occurs when the locomotive and tender are on a substantially straight track, but when the locomotive is rounding a sharp curve one end portion of the trough, generally the rearward end portion, swings laterally to the extent that in many instances a tender trough compartment 55 wide is necessary. 1n order to provide for this maximum lateral movement of the trough, in past practice, the compartment sidewalls have been arranged in parallelism and spaced apart the maximum width necessary. The height of the compartment depends upon the location of the locomotive and tender decks and in most instances is more than ample to allow vertical movement of the stolrer trough such as occurs when the locomotive and tender passes over switches, frogs, or turntables.

ln carrying out the invention the trough compartment is formed in what for convenience of description is called a compartment member which is a unitary part, preferably a casting, veither formed integrally with the tender base frame or separate therefrom if desired. The novel form of the compartment member and its advantages will appear from the following description and the accompanying drawings, in which Fig. 1 is a central longitudinal section through the rearward portion of a stolzer equipped locomotive and the improvedV tender, therefor;

Fig. 2 is a sectional view taken on the brolien line 2-2 of Fig. 1;

Fig. 3 is a section taken on the line 3-3 of Fig. 2;

Fig. 4 is al Jartial view similar to Fig. 1 showing a modication of the invention; and

Fig. 5 is a sectional view taken on the line 5 5 of Fig. 4.

The locomotive is indicated generally at A; the improved 'tender at B having the fuel section C, the water section D, the base frame E, and a novel stolzer trough compartment member F formed centrally of and longitudinally within the water section above the frame at the front end portion of the tender beneath the fuel section.

1n the embodiment of our invention shown in Figs. 1 to 3, lthe compartment member F is formed integrally with the frame E. The member F comprises the longitudinally eX- tending upright sidewalls 10, a, the transverse upstanding front and rear walls 11 and 12 respectively, an imperforate bottom Awall 18, and a centrally apertured top wall 14 all of which are integrally constructed and are arranged to form the water tight Stoker trough compartment 15. A flange 16 bounding the opening 17 is carried by the top wall 14 to which the fuel and water section partition plates 18 are attached in a manner to provide a closure with the compartment member between the two sections. The front wall 11 is fixed with the front plate 19 of the tender to form a closure for the water section at the front end of the tender.

Shifta-ble plates 20 are arranged in the opening 17 of the top wall of the compartment member to control the feed of fuel from the fuel section to the stolrer trough 21 movably mounted within the compartment 15. lnasmuch as the trough per se forms no part of our invention it will not be described in detail. 1t is of a well known form in this art and carries a suitable conveyor screw 22 for advancing the fuel from the tender to a conduit member such as the riser tube 23 rigidly attached on the locomotive A by the brackets 24 and 25 to the irebox backwall 26 through Aso which the fuel is fed to the lire. The screw 22 is driven from any suitable source of power, not shown, through drive mechanism comprising, in the construction shown, the gea-ring 40 and the shaft 4:1.

The trough 21 at its forward end is flexibly and fixedly attached to the riser tube 23 and forms therewith a universal connection as at 27. The rearward end of the trough is movably supported within the compartment 15 from the compartment member F, and, in the instance shown, swivelly mounted by means of a pair of rollers 28, 29, running upon tracks 30, 31, which tracks as shown are formed in the floor 13, closely adjacent the sidewalls of the compartment member. The rollers 28, 29, are disposed opposite each other and constitute a fulcrum point about which the trough swings laterally when the locomotive is rounding a curve or revolves vertically when passing over a turntable or rough track.

lfVith the position of the rollers 28 and 29 as shown on the drawings, that portion of the trough rearward of the rollers 28, 29 moves a greater lateral distance within the compartment 15 than that part of the trough forward of the rollers. In order to minimize the space occupied by the compartment member F within the water section the sidewalls 10 and 10a at their forward end portions are spaced apart a distance just slightly greater than the lateral movement of that portion of the trough forward of the rollers and the rearward portion of the sidewalls 10 and 10a flare laterally outwardly from their forward portion to allow for the greater lateral movement of that portion of the trough rearward of the rollers.

While in most stoker installations of the class described, the rearward portion of the trough has the greater lateral movement, positions of the rollers 28, 29, other than that shown may make it desirable to flare the forward portion of the sidewalls 10 and 10a laterally outwardly from their rear portion, or the invention contemplates laterally outwardly flaring both the rear and forward portions of the aforesaid sidewalls from a point opposite the rollers in such installations where the lateral movement of trough is substantially the same either side of its fulcrum point.

In like respects to the flaring of the compartment member sidewalls and for the same purpose, the rearward port-ion of the floor 13 thereof extends downwardly from its forward portion to allow for the greater vertical movement of that portion of the trough rearward of the roller 28, 29. The forward end portion of the floor 13 at the front end of the tender is spaced closely adjacent the bottom of the trough 21 and the distance between the two is just suiiicient to permit free vertical movement of the trough. 1n the broader aspects of the invention it contemplates eX- tending downwardly that portion of the floor of the compartment member beneath that portion of the trough having the greater vertical movement. In effect the aforesaid wall formation provides a compartment one end portion having a greater vertical and horizontal dimension than its other end portion.

By forming the floor 13 closely adjacent the trough 21, the space between the floor and the frame member E is-utilized for water and the sidewalls 10,10@ and the rear wall 12 are apertured as at 32 and 33 respectively below the floor 13 thereby providing a passage for water between the opposite sides of the water section D beneath the trough compartment 15.

Figures 4 and 5 illustrate a modied form of the invention wherein a compartment member G is constructed as a unitary member, preferably a casting, separate from the frame E, and which member is securely held to the frame by welding or suitable attachment means through the laterally extending footor pad 34. j Otherwise the compartment member G is the same as the member F heretofore described.

l/Vhile the foregoing more particularly describes our novel tender construction as with a swinging type of stolzer trough it is to be understood the invention in its broader aspects is capable of use with other types of stolrer troughs with which the inventive idea of minimizing the space occupied by the trough and its water tight compartment member can be employed as defined by the appended claims.
